Dual Closed-Loop Speed Control PI Controller for Permanent Magnet Synchronous Motor and its Improving Design

以永磁同步电机(PMSM)为控制对象,分析传统电流环、速度环控制下的PMSM动态性能。在传统双闭环控制的基础上,进一步研究电压前馈解耦环节的引入对控制器造成的影响。建立上述两种PMSM矢量控制(FOC)系统仿真模型,仿真结果表明,电压前馈环节的引入提高了该控制系统的动态性能和稳态性能。

TTaking permanent magnet synchronous motor(PMSM)as the control object,analyze the dynamic performance of PMSM under traditional current loop and speed loop control.On the basis of traditional double closed-loop control,further research is conducted on the impact of the introduction of voltage feed forward decoupling on the controller.Establish simulation models for the two PMSM vector control(FOC)systems mentioned above.The simulation results show that the introduction of voltage feed forward improves the dynamic and steady-state performance of the control system.
